The Story: From this site.When a child’s bones are found on a desolate Norfolk beach,
Detective Chief Inspector Harry Nelson calls in forensic archaeologist
Dr Ruth Galloway. Nelson thinks he has found the remains of Lucy
Downey, a little girl who went missing ten years ago. Since her
disappearance he has been receiving bizarre letters about her, letters
with references to witchcraft, ritual and sacrifice.
The bones actually turn out to be two thousand years old but
Ruth is soon drawn into the Lucy Downey case and into the mind of the
letter writer, who seems to have both archaeological knowledge and
eerie psychic powers. Then another child goes missing and the hunt is
on to find her. As the letter writer moves closer and the windswept
Norfolk landscape exerts its power, Ruth finds herself in completely
new territory – and in serious danger.

An excerpt:Waking is like rising from the dead. The slow climb out of sleep, shapes appearing out of blackness, the alarm clock ringing like the last trump. Ruth flings out an arm and sends the alarm crashing to the floor, where it carries on ringing reproachfully. Groaning, she levers herself upright and pulls up the blind. Still dark. It's just not right, she tells herself, wincing as her feet touch the cold floorboards. Neolithic man would have gone to sleep when the sun set and woken when it rose. What makes us think this is the
right way round? Falling asleep on the sofa during Newsnight, then dragging herself upstairs to lie sleepless
over a Rebus book, listen to the World Service on the radio, count Iron Age burial sites to make herself sleep and now this; waking in the darkness feeling like death. It just wasn't right somehow. Read more here.
